Unit 2417, Mechanically cut fabrication materials under
supervision; or demonstrate equivalent knowledge and skills.
Explanatory notes
1
This unit standard is for people who are performing mechanical cutting operations
using powered equipment under supervision in the fabrication industry.
2
The fabrication industry involves working with a wide range of material types, shapes
and thicknesses. Material types include low carbon and alloy steels, stainless steels,
aluminium alloys, copper alloys, and plastics. Shapes include sheet, plate, and
sections.
3
This unit standard is
For credit, assessment must involve
more than one material type, more than one
expiring
shape, more than one thickness, with a material range of either:
a
or
b
4
0.4mm to 6mm sheet and plate
–
light walled pipe
–
small structural section, angle, and rolled hollow section;
3mm plate upwards
–
heavy walled pipe
–
large cross sectional angle, beam and rolled hollow section.
Assessment must be across a range of mechanical cutting operations. Mechanical
cutting machines may include guillotines, croppers, cutoff saws, drop saws, punches
and notchers, jig saws, band saws and bevellers. Power may be electrical,
mechanical, pneumatic or hydraulic with control systems being manual or computer
operated.
